The Geographical Variation of Southern African Birds

Due for Publication in the First quarter of 2012

The aim of this publication is to illustrate the plumage differences, or geographical variation of southern African bird subspecies. This will be the first regional guide in the world to depict subspecies in Field Guide format, a project that the Trustees of the John Voelcker Bird Book Fund hope will inspire experienced birders to learn more about regional plumage differences.

History

Over 4 years has been spent selecting skins that show sufficient plumage variation to illustrate. Ingrid Weiersbye, the sole artist for the project, has meticulously captured the subtle plumage differences and jizz of these southern African races. Ten of thirteen Bar-throated Apalis subspecies for example have been illustrated. The criteria for skin selection has been 'if you can see the plumage differences in field' - then we have illustrated them!

Book design and layout

As with Roberts Bird Guide and Roberts KNP Guide, book layout and design has been done by Guy Upfold. All maps for this publication have been prepared by Guy.
